Cation-Exchange IC Columns
A complete family of columns for inorganic cations and amines
You'll get high-resolution separation of inorganic cations, ammonium, and amines using these Thermo Scientific™ Dionex™ IonPac™ cation-exchange columns. They are excellent for separations of alkali metals, alkaline earth metals, alkylamines, alkanolamines and biogenic amines.
Cation-exchange IC columns
Column | Recommended use | Target applications |
|---|---|---|
| Dionex IonPac CS21-Fast-4µm IC Column | High-resolution separation of quaternary amine cationic polar pesticides in the presence of the six common cations. Featuring high-capacity, weak cation-exchange and reverse-phase properties, the column is compatible with 100% aqueous eluents and 100% acetonitrile without loss of performance. Requires high-pressure IC for faster runs using higher flow rates. This column is a successor to the Dionex IonPac CS17 column. | Analysis of cationic pesticides (diquat, paraquat, clormequat, mepiquat, and others) in food, beverages, agricultural products, soil and environmental samples by IC-MS/MS or IC-HRAM-MS. No derivatization required. |
| Dionex IonPac CS20 IC columns | High-capacity column for common cation and amine analysis. Complementary column to the Dionex IonPac CS18 and Dionex IonPac CS19 that elutes amines away from interfering matrix ions. Requires high-pressure IC. | Group I and Group II cations, and amines including methylamines, ethylamines, ethanolamines, and alkanolamines in diverse sample matrices. Tolerates acidic samples. |
| Dionex IonPac CS19-4µm IC Columns | High-resolution separation of cations, small polar amines, moderately hydrophobic amines and polyvalent amines. Requires high-pressure IC for faster runs. This newer column replaces the Dionex IonPac CS18 column. | Common cations and amines in environmental and power plant waters, chemical process and refinery scrubber solutions, personal care products, and food and beverage samples. |
| Dionex IonPac CS19 IC Columns | For common cations, small polar amines, moderately hydrophobic amines, and polyvalent amines. Operates under 3000 psi on standard IC systems. This newer column replaces the Dionex IonPac CS18 column. | Common cations and amines in environmental and power plant waters, chemical process and refinery scrubber solutions, personal care products, and food and beverage samples. |
| Dionex IonPac CS18 IC Columns | Low-capacity column for gradient separation of polyvalent and moderately hydrophobic amines in complex matrices using aqueous eluents and elevated temperature. | Polar amines (alkanolamines and methylamines) and moderately hydrophobic amines (biogenic amines, diamines and polyamines) in diverse sample matrices, including foods and beverages. |
| Dionex IonPac CS17 IC Columns | Gradient separation of polyvalent and more hydrophobic amines, biogenic amines, and diamines. This newer column replaces the Dionex IonPac CS14 column. | Hydrophobic amines in complex matrices without solvent, such as environmental and power plant waters, chemical process and refinery scrubber solutions, personal care products, and food and beverage samples. |
| Dionex IonPac CS16-4µm and CS16-Fast-4µm IC Columns | Highest-capacity, high-resolution cation columns to analyze disparate concentration ratios of closely eluting cations such as sodium and ammonium in complex matrices. Requires high-pressure IC for faster runs using higher flow rates. | Short-chain amines and trace-level ammonium with high sodium concentration (and vice-versa) in complex industrial samples. Best cation column for low pH samples. |
| Dionex IonPac CS16 IC Columns | Highest-capacity cation column to separate high- to low-concentration ratios of sodium and ammonium in complex sample matrices. This newer column replaces the Dionex IonPac CS15 column. | Short-chain amines and trace-level ammonium with high sodium concentration (and vice-versa) in complex industrial samples. |
| Dionex IonPac CS15 IC Columns | Moderate-capacity column with unique selectivity for samples with high ammonium to low ethanolamine ratios. The Dionex IonPac CS16 is a newer, ideal alternative to this column. | Ethanolamines and ammonium cations present in disparate concentration ratios in diverse sample matrices. Ethanolamines elute before ammonium. |
| Dionex IonPac CS14 IC Columns | Moderately low-capacity cation-exchange column for analysis of aliphatic amines, aromatic amines, and polyamines using MSA or sulfuric acid eluents. The newer Dionex IonPac CS17, CS19 and CS19-4µm columns are newer alternatives to this column. | Aliphatic amines and Group I and Group II cations in diverse sample matrices. |
| Dionex IonPac CS12A IC Columns | Separation of mono- and divalent cations including manganese. Use Dionex IonPac CS16 column for high- to low-concentration ratios of adjacent eluting cations. | Common cations and ammonium in drinking water, process waters and industrial samples. Trace cations in various matrices. |
| Dionex IonPac CS12 IC Columns | High-capacity column for fast isocratic separation of common inorganic cations in diverse matrices. The Dionex IonPac CS12A column is a newer alternative to this column. | Fast, isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium using methanesulfonic or sulfuric acid eluents in diverse sample matrices. |
| Dionex IonPac CS11 IC Columns | Low-capacity, cation-exchange column for isocratic separation of inorganic cations using HCl with DAP eluents. The Dionex IonPac CS12A column is a newer alternative to this column. | Common inorganic cations and aliphatic and aromatic amines in diverse industrial sample matrices. |
| Dionex IonPac CS10 IC Columns | Low-capacity, cation-exchange column for isocratic separation of inorganic cations using HCl with DAP eluents. The Dionex IonPac CS12A is a newer alternative to this column. | Common inorganic cations and aliphatic and aromatic amines in diverse industrial sample matrices. |
| Dionex IonPac SCS 1 Silica Cation Separator Columns | For nonsuppressed conductivity detection or single-column IC (SCIC). Recommended when extended calibration linearity for ammonium or alkanolamines is required. | Common inorganic cations, ammonium, select alkanolamines, and transition metals such as zinc and copper. |
| Dionex IonPac CS5A IC Columns | Accurate simultaneous determination of common transition and lanthanide metals; high-sensitivity and selectivity in combination with postcolumn derivatization and visible detection at 530 nm; also used for aluminum analysis. | Analysis of transition and lanthanide metals in a variety of sample matrices including high-purity water, plating bath solutions, and power industry waters. |
